Get matched with top roofers in Blacksburg, SC

The cost to replace a roof typically ranges from $8,700 to $22,000, with a national average of around $9,200. The total cost depends on the size of your roof and whether you need a full replacement or can simply place new shingles over the old ones. A full replacement, which is necessary if the roof is several decades old or has multiple layers, is more expensive. This process involves tearing off the old roofing materials, inspecting and repairing the underlying structure, and then installing the new roof.

You can replace a roof in the winter, though it’s not the most popular time to do so. The biggest drawback of winter roofing work is the weather. Snow and ice make for dangerous, slippery working conditions. Plus, shingles can only be installed in temperatures above 40 to 45 degrees. 

The best time to replace a roof is in the spring or fall when the weather is mild. However, you can likely save some money by booking the job in the winter off-season, when roofers have more availability. 

Roof underlayment usually lasts as long as the roofing material that covers it, as it’s not directly exposed to the elements. In most cases, roofing companies will replace the underlayment each time they install a new roof. In some cases, particularly with slate, clay, or certain metal roofs that can last 50 to 100 years, your underlayment may require replacement within that timeframe, especially if you start to notice roof leaks.

Using an ice and water shield underlayment under a metal roof is a good way to protect the roof and your home from damage in colder climates that see a lot of winter weather. Traditional underlayment isn’t effective underneath a metal roof, though, so be sure to install one specifically made for metal roofs to get the best protection.
